So I'm making a house mod. It's pretty cool and it should be done in a week or so. However I'm having some trouble with some of the more complicated stuff like mannequins and bookshelves. When I copy a mannequin from a different house it will appear and everything, and will act immobile like a mannequin, however I can't activate it. When I follow the tutorial on the CK wiki to the letter, it appears normally but acts like a human and is rooted to the spot.

Bookshelves also appear however I can't activate them. The prompt to activate them is there however, it just doesn't do anything when I press "e".

If anyone can help I'd be very appreciative and you will be included in the credits of my mod when I upload it.
